Hello,

You have to add this custom css:

@media (min-width: 1199px){
.header_container.cl-transparent {
    position: absolute;
}

}
@media (max-width: 1199px){
.cl-mobile-menu-button {
display:inline-block !important;
}
.header_container .header-row #navigation {
    display: none;
}
}

Let us know.

Regards!
